How do plant make their lives own food

Chemistry
1 answer:
vfiekz [6]3 years ago
5 0

Answer:

Plants, like all living things, need food to survive. Plants make their food using a process called photosynthesis, which means “putting together through light.” During photosynthesis, a plant traps energy from sunlight with its leaves. It also takes up water from its roots and carbon dioxide gas from the air.

How much more acidic is a person’s blood if it has a pH of 7.3 compared to its preferred 7.4? How much more alkaline is a person
enot [183]

Answer:

0.1 and 0.2.

Explanation:

The person's blood is 0.1 decreases and become more acidic if it has a pH of 7.3 compared to its preferred 7.4 while on the other hand, the person's blood is 0.2 increases and become more alkaline it has a pH of 7.6rather than its preferred 7.4. There is 0.1 decrease and 0.2 increase in the pH of the person's blood. If the pH decreases so it means it moves towards more acidic whereas, if the pH increases there is moves towards alkaline.

Help me with this please I need the answers ASAP
Tema [17]

Answer:

1. Exothermic reaction

2. Is being released

3. The energy comes from the change in energy between reactants and products

Explanation:

The reaction is producing energy. A reaction that produce energy is called a <em>Exothermic reaction.</em>

<em />

As the energy is produced, the energy is being <em>released.</em>

<em />

As you can see in the image, the energy of the reactants is higher than the energy of the products. This change of energy in the chemicals produce the production of energy as heat.

10. What could the pH of a solution be if a cyanidin indicator turned blue? What is used to determine the endpoint of a titratio
Leviafan [203]

Answer:

The cyanidin indicator turns blue within a pH range of 5 - 7. The pH of the solution could be 5, 6 or 7.

An indicator is used to determine the endpoint of a titration.

Explanation:

Cyanidin indicator changes colour with each change in pH. In acidic solutions (pH < 7) cyanidin indicator will turn red, through to purple and blue, while in basic solutions (pH > 7), cyanidin indicator will change colour from aquamarine through to green and yellow. The cyanidin indicator turns blue within a pH range of 5 - 7.

Titration is a technique used in analytical chemistry to determine the unknown concentration of a solution. A solution of known concentration is added from a burette to the solution of unknown concentration until the reaction between the two solutions is complete. This known as the endpoint of the experiment. The endpoint of a titration is determined using an indicator which is added to reaction mixture. A colour charge is produced by the indicator at the endpoint of the reaction.

Note: An indicator is a dye of weak organic acids or bases which changes colour with changes in the pH of a solution. Some common indicators are methyl orange, methyl red, phenolphthalein, etc. These indicators are used to monitor the changes in the pH of solutions during a reaction.
